2469	SANN	Sannaite - A type of lamprophyre. In the Rock Classification Scheme, it is a lamprophyre in which orthoclase is the dominant feldspar, feldspar dominates over feldspathoids, and the predominant mafic minerals are amphibole, Ti-rich augite, olivine, and biotite. British Geological Survey Research Report RR/99/06, section 6.7 and figs. 31, 32.

2470	SAPEL	Sapropelite - A type of sedimentary-rock rich in organic matter. Sapropelite and cannel-mudstone are both derived from the unlithified fine organic mud termed sapropel. These sapropels contain more inorganic matter and plant matter than the sapropels that form sapropelic coals. Inorganic sedimentary rocks rich in sapropel are classified according to their type of organic matter. Sapropelite is rich in alginite, whereas cannel-mudstone is rich in miospores. The total organic carbon content (TOC) can vary from less than 1% to as much as 81% in a sapropelite from Tasmania, although most sapropelites fall in the range of 8 to 55% TOC. In the Rock Classification Scheme, it is recommended that the lower limit for sapropelite should be 8% TOC and the upper limit 50% TOC. A sapropelite can be recognised in hand specimen by its bituminous smell and by the curled sliver of rock produced when it is scraped with a pen knife. Sapropelites can be subdivided into lamalginite and telaginite by reference to the properties of the organic matter. British Geological Survey Research Report RR/99/03, section 6.3, table 18 and fig. 10. Synonym: oil shale.

2471	SAPRO	Saprolite - A type of regolith. It consists of highly to completely weathered materials derived from the in situ alteration and decomposition of parent rock mainly by chemical weathering processes, but which retain evidence of the original rock texture, fabric and structure. It may be classified as engineering soils falling into rock weathering grades IV (highly weathered) and V (completely weathered); that is, those weathering grades where more than 50% of the parent rock material is decomposed or disintegrated to soil.

2472	SARCST	Silicate-claystone - A type of silicate-mudstone. In the Rock Classification Scheme, it is a silicate-mudstone consisting of greater than 50% clay-grade particles. The rock is extremely fine-grained with a homogeneous appearance. British Geological Survey Research Report RR/99/03, section 2.3 and table 1.	R	Silicate-claystone			GRBA	24-FEB-00	TMCM	08-MAR-19		Argillaceous sedimentary rock with particles >50% from pre-existing siliceous rocks & particles >50% or predominantly clay-grade, <0.004mm.	C
2473	SARS	Siliciclastic arenaceous sediment - In the Rock Classification Scheme, these are siliciclastic sediments that are predominantly in size range 32 µm - 2 mm, with less than 75% of clasts smaller than 32 µm and less than 25% larger than 2 mm.

2478	SBAREN	Sublithic-arenite - A type of arenite. In the Rock Classification Scheme, it is defined as shown in British Geological Survey Research Report RR/99/03, section 2.2 and figs. 3, 4.

2483	SCH	Schist - A type of metamorphic rock with unknown protolith based on textural attributes. In the Rock Classification Scheme, it is defined as a medium-grained strongly foliated rock that can be readily split into flakes or slabs due to the well-developed preferred orientation of the majority of the minerals present, particularly those of platy or prismatic habit. Schists occur characteristically in areas of medium-grade metamorphism and can encompass a wide range of lithologies. Note that orthoschist indicates a rock that is thought to have an igneous protolith, and paraschist indicates a rock that is thought to have a sedimentary protolith. British Geological Survey Research Report RR/99/02, sections 3.3, 6.1 and fig. 1.
